But that is the guarantee of The Dream Lodge Group, which has seven UK holiday parks and will announce its eighth at next month's Ideal Home Show. Dream Lodge parks began as mobile home parks in the 1960s but have gone upmarket.
The mobile homes on most of the parks have long been replaced with lodges and while wooden holiday homes once lasted only 10 or 20 years, these days wood and resin composite lodges have a 100-year life expectancy. As a result, owners are granted a licence to keep them for 50 years without buying new ones.
"Seven years ago we decided that lodges were the future and we have pushed the standard through the roof," says Graham Boswell, the company's Lodge Investment Specialist.
He says new luxury lodges on Dream Lodge parks are built to modern housing standards, with high thermal efficiency: "They are timber-framed houses that happen to be on wheels." Those wheels are extremely important because it means there is no stamp duty or VAT to pay, even though the lodges can be lived in or rented year-round.
And it is with holiday lets that the company, and the owners, make money. With interest rates stuck firmly in the gutter, investors are searching elsewhere for opportunities to invest their savings. One popular strategy is the buy-to-let market, you or if you have the funds available you buy a property and then get an income from the rent. With property prices still rising, it's a technique that offers a degree of security whilst still returning decent returns on your investment. Sadly, you need to be aware of potential problems.

Investors can buy a lodge outright, or buy a half or quarter share.
Full ownership entitles investors to eight weeks' holiday in any of the company's parks, while half-ownership gives four weeks and a quarter two. Most Dream Lodges are built by Pathfi nder Homes, which can also organise the interior design.
As a result some are "dressed" like beach houses or boutique hotel rooms, and investors can buy everything from bedding to teaspoons. This year Dream Lodges is aiming for £3.5m worth of holiday lets, but its long-term target is £20m a year.
"We know the market is there," says Boswell. "For us to take £20m of sales we calculate how many beds we need. We buy the parks but we look for investors to buy the lodges. It is not quite venture capital but is that sort of thing."
So why would you buy a property that you don't intend to use yourself, just so that Dream Lodges can make money by renting it out? "A lodge that gives you 8 per cent is a really good reason to invest," says Boswell.
"The lodges are going up in value but that is a bonus, and tax efficiency is another." Dream Lodges has three investment options.
Its first is to buy a lodge outright between £150,000 and £220,000 and receive a guaranteed return of 8 per cent for three years which translates into variable monthly net rental payments of £12,000 to £17,600 a year, plus six to eight weeks' holiday entitlement.
For a fixed monthly income you can invest £50,000 to £200,000 and receive £4,000 to £16,000 income per year, with two to eight weeks' lodge use.
But those taking the third option of a lump-sum return can invest £50,000 to £200,000 and get a fixed rate of 27.5 per cent: a lump sum at the end of three years of £13,723 to £54,894.
Boswell stresses that anybody considering investing should get independent financial advice, although guidance is available through the company. "It is a new investment area," he says confi dently.
"We don't need to give a guarantee of eight per cent because we know the lodges will get that - but we do anyway." Seems too good to be true? Get along to the Ideal Home Show at Olympia (March 20 to April 6) and ask for yourself.
